Past Prologue is a really strong episode. There are times in season one where I don't really feel like I'm watching DS9 yet, but not here.
This despite a basically gratuitous cameo from TNG characters.
Ugh, I hated Lursa and B'Etor in this episode. They just didn't need to be there at all. DS9 grew stronger the more it relied on what made it unique (Bajoran politics, interesting characters), instead of turning to old TNG crutches such as anomoly/forehead of the week, and random TNG guest stars.
